About this recipe: Kanom Krok is an ubiquitous street snack made in the cast iron kanom krok pan. This version is rich, custardy and consistent. Recipes vary wildly, but this one works every time. More important than the recipe, though, is having a seasoned pan and even heat. I use a charcoal brazier, but you can use a gas burner that is wide and has a low temperature setting.
